Determine whether the ratios are equivalent 2 : 3 and 8 : 7

Which is the correct excel formula for the 80th percentile of a distribution that is n(475, 33)? =norm.dist(80,475,33,1) =norm.inv(0.80,475,33) =norm.s.inv((80-475)/33)?

Use the discriminant to describe the roots of each equation. then select the best description. 2m2 + 3 = m double root real and rational roots real and irrational roots non-real roots

Suppose that g(x)=f(x+9) which statement best compares the graph of g(x) with the graph of f(x)
